Be it known that I, AXEL R. SWANSQN, a citizen of the UnitedStates, residing at Chicago, ih .che @my .of .Geek vand See lis o' Illinois, have invented -ceitaiii new ,and useful Improvements in .Sewer Valves, of which the following is aspecication.

My invention relatesvto floor drain valves aiithhas particular' reference to ,that class 10 ofdrain lvalves which have closure lmembers so that case thewater backs lupin the sewer or `in the drain the ,closure member can be seciiredltightly in position forming a water tight joint and preventing the leakage of A,15 sewage or other back water into basements (inthe like. .p f `nO'ller and further .fobject of my invention is the .provision .of a valve which is leak-,proof ,and .which when open lallows the 120 water to run .freely therethrough and which when the Water begins t0 batik up, Caused nie-Dy .times by heavy rains, or tboilgbtbe risefof waters from vflooded districts, etc.,

thelcliaiiran be closed 'byhand thereby 26 insuring a tight fitting non-leaking valve through which the sewage and back water cannot rmlv `Another. advantage of my invention is the .provision kof Va valve which can be closed ,30 byhand without theuse ,o'fa wrench or other means ofclosing and secure a tightiit- "ting closure which will prevent Athe water from draining therethrough.

The stem 23has a nut 25 on vits' lower end and a shoulder 2,6 against which a closure y member 27 labutfs, the ,saidy closure .member being a dise of material whosefedges'uoverlap I the inneiledges-of the valve vseat d8a. :'-The stem 23 is in threaded engagementwith the valve 21 so that it turns fora slight'disltanee through the member 2 1, when "the valve is openedor'closed. 4 l.

Figure` 3 illustrates ya sflightlyanodiiied 100 4:form ofv devi@ mwhich the, @remember l1i has che enlarged .upper inertie@ 1,4 .andthe seat 18a.

internally threaded guide head 18 positioned in the same manner as illustrated in Figure 1. An externally threaded valve is provided rhaving perforations 31 therethrough which terminates into the channel 20, the Valve 30 having a hexagonal central portion 32, by means of which the valve 30 is turned either by means of a wrench or by hand, as may be desired. A gasket 33 is provided, upon which the outer edge of the valve 30 seats, so that a tight joint is formed between the seat 18EL and the valve 30. rIhe grating 28 is also pro-vided having perforations 2O therethrough in exactly the' same manner as heretofore described..

In closing the device, the operator grasps the head 24 of the stem 23 either by means of a wrench or with his fingers and turns the stem 23 to the right thus in effect screwing the stem 23 into the valve 21. As soon as the friction created between the head 24 and the washer 22 ovecomes the friction of the threads between the member 21 and seat 18a, the valve 21 is turned downwarduntil the member 27 is in engagement with the As soon as the member 27 is in engagement with the seat 18a, further turning of the stem 23 causes a slight separation of the members 27 and 21 but having a tight joint so that water will not pass through between the member 21 and the seat 18a. 'It will be noted that the member 27 yand the closure member 21 are in contact with each other only for a short dimance of their surfaces so only a small amount of force is needed to turn the valve into closed positions, or opened, as may be desired. When it is desired to open the valve the stem 23 is turned to the left bringing the member 27 up against the member 21 until the friction produced between these members is suiiicient to overcome the friction between the threads in the member 21 and guide member 18 when the member 27 will be raised from the seat 18a so water can pass into the sewer.

When it is ldesired because of .heavy rains or floods to close the device the stem 23 is turned downward and the member 21 turned down into place and the stem thereupon turns to the right which has the effect of driving downward upon the member 27 until these members are seated together and the valve 27 seated upon the edge 18 of the seat 18a, which forms a water tight closure between the members 26, 27 and the seat 18a.

In the modified form of the device, shown in Figure 3 a loosening of the' valve 30 brings the lower edge of the valve up off the member 33 so that the water drains through the openings 31 into the channel 2O and down into the drain pipe. A closing and opening is effected by turning the member 32 down into engagement with the gasket 33 which is composed of lead or other soft material and forms an effective water tight joint between these two members.y

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render Vexpedient without departing from the spirit and scope of my invention.
